Echinacea plant named ‘Dixie Sun’

ABSTRACT

A new and distinct  Echinacea  plant named ‘Dixie Sun’ characterized by an amazing number of inflorescences starting in the first season, very long bloom time with excellent rebloom, a very upright, compact habit, bright orange yellow young ray florets that mature to yellow, numerous, strong stems, and excellent vigor.

Botanical denomination: Echinacea spp.

Variety designation: ‘Dixie Sun’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofEchinacea and given the cultivar name ‘Dixie Sun’. Echinacea is in thefamily Asteraceae. The new cultivar is part of a planned breedingprogram for a landscape series with compact habits and profuseinflorescences. The exact parents of this selection are unknown,unnamed, proprietary interspecific hybrids bred from Echinacea paradoxa,Echinacea purpurea, and Echinacea tennesseensis.

Compared to Echinacea ‘Sunbird’ (U.S. Plant Pat. No. 22,631), the newcultivar has ray florets that are more yellow, a flatter inflorescence,and a shorter narrower habit.

Compared to Echinacea ‘Cleopatra’, US Plant Patent applied for, the newcultivar has darker yellow ray florets that mature to medium yellowrather than yellow ray florets that lighten to cream.

This new Echinacea cultivar is uniquely distinguished by:

-   -   1. an amazing number of inflorescences starting in the first        season,    -   2. very long bloom time with excellent rebloom,    -   3. very upright, compact habit,    -   4. bright orange yellow young ray florets that mature to yellow,    -   5. numerous, strong stems, and    -   6. excellent vigor.

This new cultivar has been reproduced only by asexual propagation(division and tissue culture). Each of the progeny exhibits identicalcharacteristics to the original plant. Asexual propagation by divisionand tissue culture using standard micropropagation techniques withterminal and lateral shoots, as done in Canby, Oreg., shows that theforegoing characteristics and distinctions come true to form and areestablished and transmitted through succeeding propagations. The presentinvention has not been evaluated under all possible environmentalconditions. The phenotype may vary with variations in environmentwithout a change in the genotype of the plant.
